摘要

采用差示扫描量热法(DSC)，在非等温条件下，以15oC/min的加热速率进行单次扫描，以研究玻璃态Se90Sb10-xAgx合金(其中x = 2,4,6,8)的结晶动力学。为此，使用了Handerson基于非等温方法的单次扫描DSC数据热分析理论。测定了结晶活化能和有序参数，并讨论了这些参数对组分的依赖关系。

Application of Single Scan Differential Scanning Calorimetry Technique for Determination of Kinetic Parameters of Crystallisation in Se-Sb-Ag

A single scan has been performed in Differential Scanning Calorimetry (DSC) at a heating rate of 15oC/min under non-isothermal conditions to investigate the crystallization kinetics of glassy Se90Sb10-xAgx alloys (where x = 2, 4, 6, 8). For this purpose, Handerson’s theory based on non-isothermal method for thermal analysis of single-scan DSC data has been used. The activation energy of crystallization and order parameter has been determined and composition dependence of these parameters has been discussed.
